I've never really seriously considered having a video made before (I'm not qualified to do it myself). Do you who have one find that they help boost your sales? Do you use them for FB ads? I'd love to hear more about your experiences with them.
I find that with FB ads using the video, most people never watch the whole thing.
They do, however, get a huge amount of views on my website. We direct most of our advertising toward the site (whenever possible; i.e., we can't direct AMS ads to the site), and we've determined by site traffic that the videos are a key component toward building series branding and buzz.
Really, though, we did this because we own a recording studio and we had a free weekend and a couple of bottles of wine left over from a party the weekend before.
"Hey, didn't you learn Viking yodeling a few weeks ago?"
"Why, yes, I did."
"What if you used that to sing in Elvish?"
"That could work. Do you have a libretto?"
"Not yet, but we have wine."
